6 Claims.

This invention relates to door mountings and more particularly tomountings of the type for connecting a series of door sections as a unitso that they may be mounted and operated all together. 7

Up to the present time it has been the practice to connect door sectionsas a unit by employing trusses or the like which are cut to correspondwith the size of the door unit to be made, the trusses being orificed atcertain prescribed points so that they may be bolted to the doorsections to hold them firmly.

The disadvantages of this type of construction are that such trusseshave to be made to order after information is obtained as to what sizeof door unit is to be constructed and as a result it is impossible inmany cases to make up standard trusses that can be kept in stock andused under most circumstances. In View of this more time is necessary toproduce the door unit while, on the other hand, it is not possible toconstruct it as economically for the reason that trusses of this naturecannot then be made in slack time and stored for future use. Thesedisadvantages are overcome by the present invention through which doormounting construction is provided that can be adapted within reasonablelimits to various sized units that are to be constructed.

According to the invention, a flanged truss is provided which isdesigned to extend over a plurality of door sections to unite them as aunit, the truss being constructed so that it is not necessary to form itwith bolt holes at specified points, by including a series of baseplates which are designed to be disposed between the truss and the doorsections and a series of clamping plates designed to overlie the flangesof the truss above the base plates with bolts designed to pass throughthe door sections, through the base plates and on each sideof the trussclear of its flanges to engage with the clamping plates which overlapthe truss flanges and lock the truss on the unit. Associated with suchtruss are fittings or side plates designed to be fastened to the opposedside edges of the unit to form means of slidably connecting the unit inthe door frame where it is to be mounted, the fitting including aconnecting member cooperating with the truss and designed to moveaxially in respect thereto so as to locate the fittings at their properpoints regardless as to whether the ends of the truss are spacedinwardly from the side edges of the unit.

Referring to the drawing, A indicates a door unit designed to receivethe door mounting means according to the present invention. This doorunit is made up of a plurality of door sections, four being illustratedin the drawing and numbered I0, ll, l2 and I3. The door sections aredesigned to be connected as a unit by means of the transverselyextending trusses B, the trusses preferably taking the V-channel form asindicated particularly in Fig. 6 and formed with laterally projectingflanges I 4. As illustrated, the flanges are not orificed to form boltholes as would ordinarily be the case.

According to the invention the trusses are mounted on the door sectionsby means of a base plate l5 which takes the form of a central body 16 ofrib-like construction which extends above the plane of the projectingside aprons H, the rib-like body i6 being of a cross section that willfit up into the channel l8 of the truss as clearly shown in Fig. 5. Thusthe flanges l4 rest upon the side aprons I! of the base plate on eachside of the rib-like body I6. The rib-like member or body It functionsgenerally as a reinforcing member for the truss and will prevent theside walls of the truss from shifting inwardly under any circumstances.

The base plates are designed to be mounted on The invention will beunderstood by reference the door sections at required points and this isaccomplished by bolting them on the door sections by means of the boltsit, the bolts being designed to project through the door sections andthrough the aprons of the base plates which, as shown, are orificed asat 2B. The truss is then secured On the base plates by means of clampingplates 29 which overlap the flanges l of the truss. The bolts projectingthrough the base plates pass on each side of the truss and clear of theflanges, being designed to project through the clamping plates so thatwhen the bolts are tightened the clamping plates firmly hold the trusson the base plates, the whole being secured to the door sections bymeans of the bolts. This is clearly illustrated in Fig. 2.

As illustrated in Fig. 1, the base plates are preferably positioned tooverlap the line of juncture between each door section with two boltspassing through one door section and two bolts passing through theadjoining door section. Consequently a very firm bracing of the unitresults. Of course, the base plates may be made larger if so desired andmore than four bolts might be employed to secure it, whereas it wouldalso be understood that the structure of the base plate might be smallerand of such character as only to require the use of two bolts.

The end portions of the truss may be secured by a structure of thislatter character if desired but, on the other hand, it is preferable toorifice the flanges adjacent their ends and to pass a bolt directlythrough the flanges and door section in question at this point.

It will be clear from the preceding description that a very simple andefiicient manner of con- 1:

necting door sections in a unit is produced. It is obvious, of course,that within certain limits it is not necessary to have trussesconstructed to conform exactly with the specification of the doorsections as the securing means can be positioned at any point along thelength of the truss that is desired. Thus by employing a simple truss ofa standard length 'a series of door sections may be secured together asunits regardless of the fact that one series might employ door sectionsof a different size to others.

To complete the structure and adapt it for use as a swinging garage doorunit or the like, side plate fixtures 22 are designed to be mounted atthe side edges of the completed unit. This side plate fixture may takethe form of a chane nelled member, as shown, carrying a pintle or shaft23 which carries a roller 2% projecting la erally therefrom and beyondthe marginal edge of the unit. As shown in Fig. 3, this roller isdesigned to project into a channel guide 25 which is positioned alongthe length of the side of the door frame. In this particular instancethe door is suspended from the overhead channel suspension members 2bwhich receive the suspending straps 21 of the door unit so that when thelatter is raised the suspension straps 2? and associated parts willslide longitudinally in the chane nel suspension members 25, while theside rollers 24 will ride vertically upward in the channels 25. The sideplate fittings 22 are connected with the truss by means of laterallyprojecting shanks 29 clearly shown in Fig. 3 which are designed toproject into suitable sleeve-like guides Or bushing 28 which aredisposed within the channel i8 sliding connection is effected betweenthe shanks and the members 28. In other words, therefore, a firm andsubstantial connection between the shanks and truss is effected.

It will be apparent from consideration of this structure that the sideplate fittings and attached construction completes the door unit formounting and cooperates with the truss to provide an extremely firmmounting as it in effect constitutes a final anchoring member. Moreover,it will be clear from a consideration of Fig. 3 that whetherv the endsof the truss terminate at a distance spaced inwardly from the side edgesof the unit or whether they are spaced closer to the side edges orslightly farther away therefrom does not make any material difference,since the shanks 29 may be slid in the guides 23 until the fitting plate22 is disposed at the marginal side edge of the unit.

It is clear in the foregoing, therefore, that I have provided a doormounting structure which is both simple and efficient in constructionand avoids the necessity of manufacturing the bracing trusses to anygiven length to suit particular door units that may be required at onetime.
